To examine whether companionship affects human snack consumption, researchers recruited 18 people who were randomly assigned to 3 groups to deliver a short speech either alone in a room, in front of one human friend, or with a friendly dog. Various snacks were available, and the amount eaten was measured for each subject (10= a lot, 0=none). A graph of the results and a partial ANOVA table are shown.
